WALTER WOOD STURGIS, OF TROY. vKANSAS.

? STREET-I-LAMP Pos SPEGIFIGATION forming part .of Letters Patent No.778,283, dated December 27, 1904.

Application filed October 12, 1904. Serial No. 228,208.

To all whom it may concern:

Be it known that LWALTER WOOD STUReIs, acitizen of the United States,residing at Troy, in the county of Doniphan and Stateof Kansas, haveinvented a certain new and useful Improvement in Street-Lamp Posts; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates tov certain new and useful improvements instreet-lamp posts; and it relatesmore particularly to that class agechamber or receptacle for gasolene or other oil usedas a fuel for thelamp.

The invention relates, further, to a means employed whereby the gasoleneor oil contained within the post maybe automatically supplied byair-pressure to the burner and the supply automatically regulated.

To these ends and to such others as the invention may pertain the sameconsists in the peculiar construction and in the novel combination,arrangement, and adaptation of parts, all as will be hereinafter fullydescribed, shown in the accompanying draw ings, and then specificallydefined in the appended claims; v

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part ofthislspecification, and in which draw- 1ngs Figure lis a centralvertical section through a lamp-post embodying my invention. Fig. 2 isan enlarged detail view of the automatically-operated valve and itsconnections. Fig. 3 isa sectional view on line 3 3 of Fig. 1; and

Fig. 4 is a detail view of the plug J,"showingthe valve J. I

Reference now being had to. the details of the drawings by letter, Arepresents the post, which is made, preferably, of tubing. The

post is provided atits lower end with an imperforate cap or may ableway.

B is a section ofpiping, which in the con struction of a:gaslamp post ofstandard size would be substantially about two feet in length and ofadiameter slightly less than the diameter of the hollow interiorof thepost A, within which the lowerend of said piping B is inserted,asuitable bushing or reducer, as shown at O, being provided in be closedin any suitorder to make close connection between the inner and outertubes at their point of connection. j

D is a cap which is screwed over the lower end of the inner pipe B. i Eis a like cap secured to the upper end of said pipe B.

Gris a tube or pipe which at its upper end communicates with theinterior of the pipeB at a point near the upper end thereof and attained in the hollow interior of the post to the interior of theupperchamber, which consists of the hollow interior'of the pipe B. Saidtube K has a perforated strainer bulb at its lower end, and its upperend opens near the upper end of the pipe B, and L is a tube whichextends upward through the cap at the upper end of the pipe B andcommunicates with the burner. (Not shown.) 7

M is an automatic valve designed for use in regulating the supply ofgasolene to the burner.

In order that the construction and operation of the automatic valve Mmay be clearly understood, reference should be had to Fig. 2 of thedrawings, in which the details of this valve and its connections areclearly shown.

Referring to said Fig. 2, a is a cup attached to the upwardly-bent lowerend of the tube L within the lower end of the pipe B, and b is afloatprovided at its lower end with a valve-stem g, having at its lower end aconical valve 0, adapted when closed to be seated upon the valve-seat(Z. 00 are holes through the cup (0, which serve to admit gasolene tothe cup.

From the foregoing description of the construction of the device itsoperation will be readily understood and is as follows: In filling thechamber contained in the post A with gasolene or other oil to be used asa fuel the filler-plug J, provided with an air-valve J is removed, andafter the chamber has been filled with gasolene or other oil usedasafuel air is forced, by means of any suitable airpump, through saidair-valve J. In order to fill the tube B with gasolene, the valve H isgiven a one-quarter revolution to cause the waste-port of the valve toregister with the portion of the tube G above the valve H, thus servingto release air from the pipe B and at the same time to cut off thepassage of air from the tube A into the pipe B, the airpressure forcingthe gasolene through the pipe K from the lower end of the pipe B.

to the pipe leading to the lamp, said pipe eX- tending verticallythrough the pipe B. When the pipe B is filled with gasolene, the Heat 7)serves to hold the valve 0 from its seat (Z, permitting the gasolene toescape. As the gasolene lowers below the float b it permits the valve 0to fall back into its seat (Z, and thus serves to stop the escape ofgasolene.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, is

1. A lamp-post oil-containing reservoir and feeding apparatus comprisinga hollow post reservoir adapted to contain oil under pressure, a pipingclosed at its ends and having a valve-controlled passage-waycommunicating between the same and said reservoir, an openended tubingcommunicating between said reservoir and pipe, and a valve-regulatedexittube leading from said pipe, as set forth.

2. A lamp-post oil-containin g reservoir and feeding apparatuscomprising a hollow post reservoir adapted to contain oil underpressure, a pipe with closed ends, a valve-regulated passage-wayintermediate said pipe and reservoir, an open-ended tubing communicatingbetween said reservoir and pipe, a burnerfeeding tube positioned withinsaid pipe and lezuling through the closed top thereof, and afloat-regulated valve adapted to regulate the exit end of saidburner-feeding tube, as set forth.

3. A lamp-post oil-containingreservoir and feeding apparatus comprisinga hollow post reservoir adapted to contain oil under pressure, a closedpipe extending within said reservoir, a valve-regulated passage-waycommunicating between said pipe and reservoir, a valve filling-plug, anopen-ended tube passing through the lower closed end of said pipe andaffording communication between the reservoir and pipe, a burner-feedingtube passing through the closed top of said pipe and having its lowerend bent, a cup provided with circumferential apertures, fitted to thelower end of said burner-feedingtube, a valve having a play within saidcup and designed to close the exit-opening in the bottom of the cup, anda float secured to said valve, as set forth.

In testimony whereof I hereunto allix my signature in presence of twowitnesses.
